I also thought of that Kathy Ireland fixture..:) I have it saved as well the diameter is though smaller than what you were looking for..not that it makes it a "no"..but I remembered you wanting a bigger one you can though, besides contemplating the overhead lighting.. a) go for sconces. besides lamps etc. they're higher..gives a different feel. b) consider installing a skylight. totally changes the perception of the ceiling's height it is a personal preference..and a matter of what one's accustomed to. I grew up having overhead lights. True, our ceilings were much higher then.. Together with that, you should do the best with the space you've got I broke the rule of "no overhead lights with standard ceilings"..where I could of course..I'm happy I did-it breaks the expanse of the ceiling..brings more interest..you're less concentrating on that "oh my ceilings are low" but every room is different. some are square, some are rectangular....some are darker, some are naturally lighter..take your own unique space into account say, in the master that's kinda long, we installed a skylight...put a pendant in the corner, over the sitting area..installed sconces...also have table lamps of course in DD's room that's small and already has a skylight, we didn't hardwire anything, but I bought this vintage wall chandelier..a long sconce, essentially..it's not overhead lighting yet it looks like one...:) that brings the feeling that chandeliers usually give..and what's important is the feeling. The feeling, you can get in many ways, as I've learned... In other rooms that are either smaller or somehow more conductive to have this overhead lighting, I went with flush mounts or semi flush..it looks totally fine. They're all on dimmers-we saw to that..and there are other lamps in the rooms, table ones next to beds, and floor ones, and sconces..so you don't rely on this overhead light only..but you have it. You have layers of lighting, and it gives you all the flexibility. And you control the feel and the function..which is obviously a very good thing. That taught me there are no rules set in stone..you look at your room and you see by what means you can get the feel and the function you're after. And if it's a mix that's the best of course.

It's ok. Light appears to be pointed up, which may not light the entry as much as you'd like, but will work. Here are a few more to consider... https://www.houzz.com/products/sea-gull-lakeview-two-light-outdoor-ceiling-flush-mount-antique-bronze-prvw-vr~38687170 https://www.houzz.com/products/sea-gull-lighting-2-light-outdoor-flush-mount-black-prvw-vr~48101731 https://www.houzz.com/products/progress-lighting-2-light-fush-mount-clear-seeded-glass-curved-panel-black-prvw-vr~48540452 https://www.houzz.com/products/granville-outdoor-sconce-lighting-steel-oil-burnished-bronze-125-prvw-vr~62459164 https://www.houzz.com/products/progress-lighting-p6023-31-2-light-flush-mount-water-patterned-glass-panels-prvw-vr~13769882 https://www.houzz.com/products/livex-lighting-2184-04-outdoor-lighting-outdoor-ceiling-light-prvw-vr~8492915

I would start by retrofitting the existing square can with an LED kit that screws into the exsisting socket and that will help those produce more light than they are now. something like this: https://elcolighting.com/products/8-square-led-retrofit-insert In front of the fireplace, you could keep the existing track there and just get 2 smaller track heads for the one by the tv. its just in a very redundant spot. After you brighten up the existing cans see if you actually need that light. if you do I would put in a 4 inch recessed light with a square trim. or a single spotlight aimed at the doorways.

First, we need to address the utility part of the lighting. for example is your kitchen underlit at night? Do you read in your living room, have floor lamps? Lastly, I don't see electrical in your dining area have you established you can get it there? Oh and why are there two hanging lights in the entry? HMMM
